“Predictive Validity of Entrance Exam Stanine Scores and Academic Performance in English and Math on Career Service Exam Success Among BPA Students”

This study examined the predictive validity of entrance exam Stanine scores and academic performance in English and Math on the success of the Career Service Exam (CSE) among Bachelor of Public Administration (BPA) students at Davao del Norte State College (DNSC) from 2018 to 2024. Using a descriptive-correlational design, data were analyzed from 57 BPA graduates, including stanine scores, final subject grades, and CSE results. Spearman’s rho revealed a strong positive correlation between entrance exam stanine scores and CSE outcomes (ρ = .722, p < .001), while Pearson correlation indicated that final grades in English (r = .752, p < .001) and Math (r = .703, p < .001) were also significantly related to CSE success. Binary logistic regression showed perfect model classification, although convergence issues suggested quasi-complete separation due to small sample size and high pass rate (77.19%). The findings affirmed the relevance of cognitive and academic metrics as valid predictors of career service exam success. The study validated Messick Theory of Construct Validity and emphasized the importance of early academic profiling and subject mastery to improve employability among aspiring public servants.
